About us

Our catalysts stop around 20 million tonnes of pollutants in their tracks every year. In the automotive market, one in every three new cars carries an emission control catalyst from JM. Toxic carbon monoxide and unburned hydrocarbons go in to the catalyst, clean air comes out. And because we understand, at the atomic scale, the distribution of platinum, palladium and rhodium in our catalysts, we're able to minimise the amounts of precious metal required to do the job.

Our chemistry helps relieve symptoms in millions of people each year. Active pharmaceutical ingredients (APIs) are the constituents of pills and other medications that do all the work, whether it's attacking cancer cells, regulating a heart beat or combating severe pain. And making them effectively always starts in the lab. JM develops API processes for many important, life changing drugs. We employ highly complex chemistry to prepare molecules to very specific standards, then design advanced manufacturing methods to produce them at the scale that our pharmaceutical customers need.

Platinum group metals (pgms), are a valuable natural resource, and their applications are numerous. You'll find them in autocatalysts, jewellery, electronics and even people's mouths, as fillings. The more pgms we can reuse, the less we need to take from the earth. So we've developed highly advanced processes for extracting and separating pgms from products - so advanced that we can recycle platinum and palladium, for example, to a purity of 99.999%.

Electric vehicles are on their way, and we're developing advanced new materials for battery cells in hybrid and full electric cars. Cathodes are the key. We're engaged in the cutting-edge science needed to understand how different cathode materials can reduce the time a battery takes to charge, and extend the distance fully charged electric vehicles can travel.
